Discrete Wavelets and Multiresolution Analysis [PDF]

, 1993
Summary: In this paper we present an elementary discussion of the discrete wavelet transform. A major problem is formed by the construction of an orthonormal wavelet basis of the Hilbert space of square integrable functions. It is shown that the concept of a multiresolution analysis is very helpful to make such a construction.

Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

Geometric-textured bitree: transmission of a multiresolution terrain the Internet

Journal of Computer Science and Technology, 2002
Transmission of large terrain databases across the Internet is still worrying. A large terrain database requires a big number of polygons and textures, and that represents a problem with current bandwidth and resource limitations.

When is Fake Real Enough? Evaluating StyleGAN2 and NVAE Face Realism Across Animation and Visual Contexts

Computer Animation and Virtual Worlds, Volume 37, Issue 3, May/June 2026.
The experimental framework of our study that evaluated human perception of real versus synthetic faces generated by StyleGAN2 and NVAE architectures across static, animated, isolated, and contextualized presentation formats. The findings demonstrate that perceived facial realism is highly context‐dependent, revealing significant interaction effects ...

Learning to solve multiresolution matrix factorization by manifold optimization and evolutionary metaheuristics

Machine Learning: Science and Technology
Multiresolution matrix factorization (MMF) is unusual amongst fast matrix factorization algorithms in that it does not make a low rank assumption. This makes MMF especially well suited to modeling certain types of graphs with complex multiscale or ...

Resilient nekton composition in the face of climate‐driven foundation species shifts

Ecology, Volume 107, Issue 5, May 2026.
Abstract Climate‐driven range expansions of individual species are well‐documented, but corresponding community shifts are not. This lack of widespread community change may indicate communities can resist wholesale change with the arrival of new species.
